8 Claims.

The principal object of my invention is to provide a coin selector forpay telephones and like that will eject all slugs and spurious coinsbefore they enter the device they are intended to oper ate.

A further object of this invention is to provide a coin selector for paytelephones and like that electrically selects or differentiates betweencoins and slugs when a manually operated lever is actuated and returnsall spurious coins to the user allowing the genuine coins to fall intothe device to be operated.

A still further object of my invention is to provide a coin selector forpay telephones and like l5 that will hold the coin within the selectorunit until the manually operated lever is actuated for p theidentification of the coin.

More specifically the object of this invention is to provide a coinselector for pay telephones and like that depends upon the engraving ona genuine coin for its actuation.

A still further object of my invention is to provide a coin selector forpay telephones and like that is economical in manufacture, durable andeflicient in use.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, ar-

, rangement and combination of the various parts of the device, wherebythe objects contemplated are attained as hereinafter more fully setforth, pointed out in my claims and illustrated in the accompanyingdrawings, in which:

Fig. 1 is a side sectional view of my complete coin selector as attachedto a portion of a pay telephone.

Fig. 2 is a sectional view of a portion of my device showing the coinselectors. Fig. 3 is a top plan view of the shuttle and coin followersof my device.

Fig, 4 is a schematic wiring diagram of the electric circuit of mydevice.

Fig. 5 is a rear cross-sectional View of a portion of my device showingthe shuttle and the guide 5 bars upon which it rests.

There have been numerous attempts to create a device for the eliminationof slugs and spurious coins from pay telephones and similar coinoperated machines. The majority of these rely on a 5 magnet for pullingthe spurious coins out of the device before they operate the device.However, these devices are only successful on ferrous metals 1 and areof no value when copper, brass, nickel, aluminum or similar slugs areused. 'Also some '55 types work on the principle that all slugs have ahole in the center and these devices only eject those slugs which dohave a hole in the center. None of the devices now in use depend uponthe pecularities of the engraved portions of our coins. There has been adistinct need for a device that will successfully prevent the use ofslugs in operating slot machines. Many thousands of dollars are losteach year by owners of slot machine dispensers and automatic pay devicesthrough the use of slugs in those machines as well as loss ofmerchandise through this fraudulent means. There is the ever-presentdanger of jamming the machine, thus necessitating repairs and costlydelays. I have overcome these difficulties and supplied a need as willbe appreciated and as is hereinafter more fully set forth.

Referring to the drawings, I have used the numeral I ii to designate thehousing of my device including the housing of an ordinary pay telephonehaving situated therein a return slot II and a coin slot l2 as shown inFig. 1. The numeral l3 designates the coin entrance and as is wellknown, there are generally three of such entrances on a pay telephone,one to receive nickels, one to receive dimes and one to receivequarters. The numerals it, IS and I6 designate coin followers of theapproximate diameter of a quarter, dime and nickel respectively andconstructed of an insulating material such as hard rubber fiber or thelike. These followers each have a shaft secured to the rear centralportion and extending rearwardly and which I have designated by thenumerals l'l, l8 and I9 respectively. These shafts in turn are slidablymounted in a shuttle 29 which is of box-like construction and has itsforward and rear surfaces constructed of an insulating material as shownin the drawings.

The numerals 28, 22 and 23 designate stops secured to the rear end ofeach of the rods l1, l8 and I9 respectively which limit the forwardsliding movement of the rods and determine the extended position of thefollowers M, l5 and It. The numerals 24, 25 and 2t designate coilsprings about the rods ll, l8 and I9 and partially compressed betweenthe front surface of the shuttle 20 and the rear surface of thefollowers M, l5 and I6 respectively. I have used the numerals 21 and 28to designate guide rails secured to the housing ill of the device andupon which the shuttle 20 is slidably mounted as shown in Figs. 3 and 5of the drawings. Rigidly secured within the housing of the device andextending upwardly near its forward portion is the insulative wall'29which supports the coin plates 30, 3! and 32 which are spaced from andconcentric with the followers I4, I5 and I6 as shown in Fig. 1. Theseplates each have the electric contact fe-eler points 33, 34, 35 and 36which protrude through their respective plates a slight distance asshown. As corresponding numerals designate respective contact points andare electrically connected as shown in the schematic diagram in Fig. 4of the drawings, they will be referred to as a single unit. It will herebe noted by reference to Fig. 1 that the rearward or contact faces ofthese coin plates are directly'parallel to and under the forward wall ofthe coin slot I3 so that a coin dropping through the slot must dropbetween its respective follower and coin plate. I have used the numeral3'! todesignate a shaft slida-bly mounted within the housing of thedevice, extending through the forward wall of the device, and having onits forward end a knob 38 to facilitate the manual actuation of theshaft 31. Pivotally secured to the rearward end of this shaft is thelever 39 which has one of its ends suitably pivoted on a bearing securedto the guide rail 28 and has its other end pivotally ser cured to a link45 which is in turn pivotally secured to a bearing 4| which is rigidlysecured to the rear face of the shuttle 20 for actuating the same and asis shown in Fig. l of the drawings.

Thus by manually pushing on the knob 38 the shaft 37 will be pushedrearwardly, actuating the lever 39 and pushing the shuttle 20 forward.Positioned below and between each set of follower and coin plates is thestop and deflector plate 42 r which is pivotally secured near its lowermarginal edge to the housing Ill of the device. This deflector plate 42has a semi-circular cut-out portion which is also widened and restsadjacent the lower half of the coin plates as shown in Fig. 2 of thedrawings. Pivotally secured to the deflector plate 42 near its centralportion is the bar 43 which extends rearwardly and has its rearward endpivotally secured .to a lever 45 which is secured to the central portionof a magnet arm 45 which is, in turn, pivotally secured to the guiderail 28 as shown in Fig. 1.

This lever 441s held in its neutral central position by the opposingvcoil springs 46 which have their free ends secured to the housing andwhich tends to hold the lever in a vertical position. The numeral 41designates a fork integrally formed on the bar 43 and extendingdownwardly and which receives a pin 46 secured to a lever 49 as shown inthe drawings. This lever 55 is pivotally secured to the guide rail 28,extends up one side wall of the housing I!) of the device and has itsother end pivotally secured to a link 56 which in turn is pivotallysecured to the operating arm of a bridge switch 5| which is of thecommon. type. I have used the numerals 52, 53 and 54 to designate threecircuit breaker magnets having the breaker arms 55, 56 and 5?respectively and the contact points 58, 59 and 66 respectively as shownin the drawings. The numeral 5| designates a selector magnet operativelyarranged above the forward end of the magnet arm 45. The numeral 62designates a similar selector magnet operatively arranged adjacent therearward end of the magnet arm 45. These magnets are so arrangedthatwhen the magnet 5| is in operation the magnet arm is drawn upward atits forward end moving the lever 44 forwardly operating the bar 43.Similarly when the magnet 62 is energized, the rearward end of the arm45 is drawn upwardly. pulling thelever 44 rearwardly and actuating thebar 43. The numeral 63 designates a contact arm secured to the forwardface of the shuttle 20 as shown in Figs. 1 and 3 of the drawings. Thenumeral 64 designates the stationary contact arm secured to the guiderail 28 insulated from contact therewith, and capable of receiving thecontact arm 63 when the shuttle 26 is moved forwardly. Thus it will beseen that when the knob 38 is manually actuated, the shuttle will moveforwardly as hereinbefore described, closing the contact between thearms 63 and 64. When pressure is released on the knob 38, the rod 31will be pulled to its more forwardly position by virtue of the spring65' which has one end secured to the rod 31 and its other end secured tothe housing I as shown in Fig. 1.

Referring to Fig. 4 of the drawings, I have used the numerals 66 and 61to designate the input electric wires which are in communication with asuitable source of power such as the telephone line voltage. The wire 66is in communication with the contact points 33 of the contact plates.The numeral 68 designates a lead wire in communication between the wire66, two contacts of the switch the stationary contact 64 of the shuttleoperated switch and the breaker 55 of the electromagnet 52. The numeral69 designates a lead wire in electrical communication between thecontact points 34 of the contact plates and one end of the windings ofthe electromagnet 52 which is also connected to the lower end of thewindings of the magnets 53 and 54, to the lower end of the magnets 6|and 62 and thence connected to the wire 61 as shown in the drawings. Thenumeral I6 designates a lead wire in electrical contact with thecontacts 35 of the plates and in communication with the upper end of themagnet coil 53. The numeral ll designates an electric lead line incommuni cation with the contacts 36 of the contact plates andinelectrical communication with the upper end of the windings of themagnet 54. The numeral I2 designates a wire in communication between thecontact 58 of the magnet 52 and the arm 56 of the magnet 53. The numeralI3 designates a lead wire in communication between the contact 59 of themagnet 53 and the arm 51 of the magnet 54. The numeral 14 designates alead wire in communication between one contact of the switch 5|, thecontact 60 of the magnet 54 and the upper end of the windings of themagnet 62. The numeral I5 desig nates a lead wire in communicationbetween the contact arm 63 and the upper winding of the magnet 6|, andalso in communication with one contact of the switch 5| as is shown inthe schematic diagram. The dash lines shown in Fig. 4 designategenerally a portion of the bar 33, the lever 49 and the link 50 whichoperate the switch-5| for purposes of identification of contacts of theplate 3|. It will here be noted that all coins are engraved and arequite irregular in facial contour. Thus all four of the contact points33, 34, 35 and 36 will not be short circuited by the, coin. As the rod31 is pushed farther rearwardly, the shuttle will move foragainst thecontacts on the plate 3!.

wardly against the compression of the spring 25 until contact is madebetween the contact arms 63 and 64. This closes the circuit between thesource of current and the electromagnet Bl. The, magnet 6| thus beingenergized will pull the forward end of the magnet arm toward it,'thuspivoting this arm and moving the lever 44 in a forwardly direction. Thiscauses the deflector plate 42 to pivot forwardly and at the same timeoperates the bridge switch 5| thus keeping the magnet 6| in circuit sothat when pressure on the knob 38 has ceased, the spring will return theknob as well as the shuttle and its appendant mechanism toward itsnormal position. As the bridge contact switch holds the circuit for atime, the plate 42 will remain in its upwardly and forwardly slopedposition after the pressure on the coin has ceased, thus deflecting thecoin downwardly and through the coin chute l2 where it will operate themechanism. When the shuttle 26 is' then moved to its rearward position,the contacts within the switch 5| will open and the neutralizing springs46 will return the mechanism to a normal position as the magnet 61 willnot be energized when the switch 5| is in a normal position.

If a slug or other spurious coin is inserted in the coin slot l3, itwill take a similar position between the follower l5 and the plate 3|.However, when the shuttle is actuated by the rod 31, the follower willforce the counterfeit coin This short circuits all of the contacts 33,34, 35 and 36 thus actuating all of the magnets 52, 53 and 54 closingthe arms 55, 56 and 51 upon their respective contact points 58, 59 and60, completing the electrical circuit to the magnet 62. As the magnet 62is energized, it will pull the rearward end of the magnet arm 45upwardly thus moving the lever 44 rearwardly so that as the pressure isreleased the spurious coin will drop into the chute II which returns thecoin to the user without actuating the mechanism of the device intendedto be operated. The action of this counterfeit coin detector circuitrotates the touch on the engraving of a genuine coin, it will notactuate the return mechanism. It is very unlikely that all four contactpoints would touch a genuine coin. If, however, a smooth coin is placedin the device, it will return it to the user, so that he will not be outhis money.

It will be noted that the first pressure of the L follower --on a slugwillimmediately short circuit .all of the contacts on the coin plate,thus moving the plate 42 for the rejection of the spurious coin.Thismoves the switch 5| to hold the contact and even when the knob 38 ispushed to its rearmost position and contact is made between the contacts63 and 64 closing the circuit to the magnet 62 no counter action willtake place.

.After the magnet arm 45 has been drawn ad- .j acent to the magnet 5|the rearward end of the arm ,45 will be at such a distance from the mag.

can not possibly overcome the magnetic field of the magnet BI and movethe arm 45 in the other direction.

Thus it will be seen that I have provided a;-

coin selector for telephones and the like that will reject all spuriouscoins, slugs and Worn coins before they enter the mechanism they areintended to actuate. My device will work on any type of metallicsubstance that will conduct an electric current. It issimple to operate,having only one manual control and can not be tampered with withoutdestroying the device.

Some changes may be made in the construe tion and arrangement of myimproved coin selector for pay telephones and the like without departingfrom the real spirit and purpose of my invention, and it is my intentionto cover by my claims any modified forms of structure or use ofmechanical equivalents which may be reasonably included within theirscope;
